Analysing airport efficiency in East China using a three-stage data envelopment analysis Universiteit Antwerpen Universiteit Gent
This paper evaluates the Technical Efficiencies (TEs) of a group of airports in East China by applying a threestage Data Envelopment Analysis (DEA) method. The merit of this method allows us to consider the impact of the environmental factors on measuring airport efficiencies. Three variables, i.e. per capita Gross Domestic Product (GDP), the proportion of the tertiary industry, and the number of tourists, are used to represent the environmental ...
Assessing individual driver’s relative performance at curve: applying Data Envelopment Analysis on simulator data Universiteit Hasselt
This study investigates the performance of drivers at the individual level, at two different curves, using data from a driving simulator in order to identify the best drivers within the sample and to gain insight into the most problematic behavior of each driver. To this end, 34 participants varying in age and gender completed two particular simulator scenarios and their speed, acceleration and lateral position, were monitored at various points. ...
Efficiency Analysis of Road Safety Pillars by Applying the Results of a Structural Equations Model in Data Envelopment Analysis Universiteit Hasselt
Assessment of road safety performance of countries and their comparison is essential in guiding future decisions. The objective of this study is to search for effective safety pillars in road safety capacity strengthening based on the experiences of the leading countries. In this study, we first try to use the results of a structural equations model with partial least squares approach to select the index as the representative index of each road ...
Road safety risk evaluation and target setting using data envelopment analysis and its extensions Universiteit Hasselt
Currently, comparison between countries in terms of their road safety performance is widely conducted in order to better understand one's own safety situation and to learn from those best-performing countries by indicating practical targets and formulating action programmes. In this respect, crash data such as the number of road fatalities and casualties are mostly investigated. However, the absolute numbers are not directly comparable between ...
Modeling qualitative data in data envelopment analysis for composite indicators Universiteit Hasselt
Composite indicators (CIs) are useful tools for performance evaluation in policy analysis and public communication. Among various performance evaluation methodologies, data envelopment analysis (DEA) has recently received considerable attention in the construction of CIs. In basic DEA-based CI models, obtainment of measurable and quantitative indicators is commonly the prerequisite of the evaluation. However, it becomes more and more difficult to ...
Fuzzy data envelopment analysis in composite indicator contruction Universiteit Hasselt
Data envelopment analysis (DEA) as a performance evaluation methodology has lately received considerable attention in the construction of composite indicators (CIs) due to its prominent advantages over other traditional methods. In this chapter, we present the extension of the basic DEA-based CI model by incorporating fuzzy ranking approach for modeling qualitative data. By interpreting the qualitative indicator data as fuzzy numerical values, a ...
Benchmarking road safety: Lessons to learn from a data envelopment analysis Universiteit Hasselt
Road safety performance indicators (SPI) have recently been proposed as a useful instrument in comparing countries on the performance of different risk aspects of their road safety system. In this respect, SPIs should be actionable, i.e. they should provide clear directions for policymakers about what action is needed and which priorities should be set in order to improve a country's road safety level in the most efficient way. This paper aims ...
Traffic fatality indicators in Brazil: State diagnosis based on data envelopment analysis research Universiteit Hasselt
The intense economic growth experienced by Brazil in recent decades and its consequent explosive motorization process have evidenced an undesirable impact: the increasing and unbroken trend in traffic fatality numbers. In order to contribute to road safety diagnosis on a national level, this study presents a research into two main indicators available in Brazil: mortality rate (represented by fatalities per capita) and fatality rate (represented ...
On variable reductions in data envelopment analysis with an illustrative application to a gas company Universiteit Hasselt
Data envelopment analysis (DEA) is a non-parametric data oriented method for evaluating relative efficiency of the number of decision making units (DMUs) based on pre-selected inputs and outputs. In some real DEA applications, the large number of inputs and outputs, in comparison with the number of DMUs, is a pitfall that could have major influence on the efficiency scores. Recently, an approach was introduced which aggregates collected inputs ...
